Abstract: |
This
work contains the simulation results of vortex ring state appearance and evolution
around main rotor of a helicopter. These calculations were based on solution
of Navier-Stokes equations using the Fluent code.
During these simulations an actuator disc model of fan has been used. This
model assumes that a fan is a pressure jump generating
surface. Two meshes have been used during this simulation: three dimensional
and axisymmetric two dimensional.
The most of the cases has been calculated using steady flow solution, but
unsteady model also has been applied. Main goal of this work was a
calibration of model, in terms of simplifications influence on results, and
also in comparison with experimental results. It is assumed, that after a
proper calibration, this model can be used in further flight safety methods
of VRS elimination research. |
